Step 1
Given: N = 200 turns I = 4 A L = 1.5 m Substituting these values into the formula, we get: B = (4π x 10^-7 T·m/A) * (200 turns) * (4 A) / (1.5 m) Calculating this expression, we find: B ≈ 0.033 T Show more…

"A coil consists of 200 turns of wire. Each turn is a square of side d = 40 cm and a uniform magnetic field directed perpendicular to the plane of the coil is turned ON If the field changes linearly from 0 to 0.8T in 10s, (a) What is the magnitude of the Induced 'emf' in the coil while the field is changing? (b) Also , find the Induced 'currentin the coil, if resistance of the coil is 3.0n ?"
